The details of the-interlock are best'shown in 45 In terms of broad inclusion, the interlocking Figure 3. Here it is seen that the tab 4 or one shingle embodying our invention comprises a, shingle engages the ec ving slot 3 of an ad sheet having a receiving slot at one corner and jacently laid shingle, and that the slit Ii engages a locking tab at an adjacent corner adapted to the portions of the adiacently laid shingle above engage with the slot of an adjacently laid shin the receiving slot 3. This forms a double inter- 50 gle. A slit is also provided adjacent the tab for lock and restrains the shingles against relative further engagement with the portlonspf the admovement in three directions; viz., against lateral jacently laid shingle near the receiving slot. This relative movement in both directions and against forms a double interlock which restrains the invertical relative'movement in one direction. This 5 terlocked shingles against relative movement in is a material improvement over the ordinary tab and slot interlocks, because the latter' restrain the shingles against relative movement in two directions only; viz., against lateral relative movement in one direction and against vertical relative movement in one direction. The double interlock of our invention is as simply engaged as the ordinary interlocking means, and not only provides a more secure and permanent fastening,

but also serves to more ilrmly hold the shingles against movement when they are being shifted into alignment and nailed.

As best shownin Figure ,4, a nail I2 is driven I through the corner of the shingle adjacent the receiving slot 3,'and a secondnail i3 is driven through the oppositevcorner. In order to facilitate laying the shingles, meansare'provi'ded for i V aligning the shingles inposition, and in order to save time and avoid unnecessary movements on the part of a workman the aligningmeans' is posiproper position;

tioned adjacent the point where theflrst nail is driven.' A suitable'marker; such as the notch M;

is formed on the side edge of the shingle adjacent the receiving slit 3 This notch is positioned to register-with the upper edge of the underlying shingleuwhen the-shingle Thus, when ashingle is being laid it is first v slipped intol'interlocking engagement with'the previously laidshingle, and thenthe shingle is shiited:until the notch il is in the. proper position. At this time" the workman-s eyes and at least one hand'is in the region about the corner oi the'shingle having thereceiving slot, and,

since the nail I2 is driven first,- unnecessary movements back to this position when the. nail is driven are "eliminated; workmen are accustomed 'to' driving the nail I! first when laying interlocking shingles, because it gives the m angopportunity to keep thebottom edge of the shingle of others in the same course. The

theyare nailing inline'with the bottom edges ll is thendriven.

Another'im'portant feature or the above described aligning means-is that the marker is positioned substantially the maximum distance possible away from the interlocking cornerabout which the shingle pivots when it is being shifted into alignment. This arrangement reduces errors being'laid is in the; g g between thetab andside edge, andaslot extendsecond nail in alignment and results in a more accurately positioned shingle. A second notch I6 is also preferably provided along the edge of the shingle and spaced from the notch ii. :If this second notch is used for alignment a greater degree of overlap is secured.

'Figure' 6 shows a variant .form of the interlocking means embodying our invention. In this construction the tab llprojects outwardly irom the side edge I! and lies wholly without the body 01' the shingle; the tab being cut entirely from the corner 01 an adiacently cut shingle near its receiving slot is. In this construction a slit II is provided extending. downwardly as a continuation of theedge II and separating a portion oi the tab from the body of the shingle for engaging portions of theadjacentlylaid shingle over the receiving slot. 1
